Bacnet integration quick start

This article applies to the following CoolAutomation  products:

  • CoolMaster 
  • CoolMasterPro 
  • CoolMasterNet
  • CooLinkHub
  • CooLinkBridge

Intro

This is a quick-start guide for local BACnet integration with CoolAutomation's devices.

Coolautomation's network gateways (CoolMaster, CoolMasterPro, CoolMasterNet, CooLinkHub, CooLinkBridge) provide a full BACnet integration to various HVAC, Cooling & heating systems.

for more advanced integration options, you can refer to the BACnet integration guide.

Note!

  • Prior to purchasing a CoolAutomation device, please consult our specialist with regard to the compatibility of the connected system to the CoolAutomation device.
  • BACnet protocol license in CoolMaster, CoolMasterPro is included.
  • The usage of BACnet with CoolMasterNet, CooLinkBridge & CooLinkHub has an additional one-time cost for the BACnet license. Before proceeding with the steps below, make sure you have an active license.
  • Local service data is available only on CoolMasterPro & CoolMasterNet

 

Prerequisites

  • Download the CoolAutomation Toolbox or use any other terminal SW (Putty, built-in Windows terminal SW, etc.…)
  • Network access to the network that the device is connected to (via local TCP/IP connection) or USB Type A to Type B for local network interface enablement (USB cable supplied with CooLinkHub).
  • A computer with a network or USB connection

 

Configuration steps

Setting the VA (Virtual Addresses)

VA is the representation of each IDU (VRF or Split) in an internal BACnet point table on the Coolautomation device.

IDU representation in a BACnet table

IDU BACnet representation sample

The following is a basic control IDU representation in a BACnet table of 5 connected IDU’s (VRF or split):

Normally VA are distributed after identification of IDU on devices screen. In the case of CoolPlug & CooLinkHub layout, each IDU is represented by CoolPlug, so the VA auto distribution command must be applied after all wireless CoolPlugs are paired with respective CooLinkHub and powered. 

When CoolPlugs are installed onsite, they are powered from the AC, but during laboratory pre-set, they can be powered via a direct USB connection to CooLinkHub. The paring process is described in the "How to Pair a Wireless CoolPlug to a CooLinkHub" video tutorial and CoolPlug installation manual 

 

Distributing  VA’s

>VA auto

OK

querying the VA’s

>VA 
L1.100 --> 0001 [Hex: 0x0011 | Dec: 00017]
L1.101 --> 0002 [Hex: 0x0021 | Dec: 00033]
OK

 

Query BACnet settings

In the terminal window enter the "bacnet" command 

>bacnet 
Dev instance: 64 (0x000040)
BACnet IP:    enabled
UDP port:     47808 (0xBAC0)
BACnet MSTP:  L3
TS address:   64 (0x40)
OK

 

BACnet IP Integration

CoolMaster & CoolMasterPro can be configured via the touch screen. Please refer to the CoolMaster user manual and review the BMS setting chapter

Activate BACnet IP

bacnet ip enable
OK, Boot Required!
Boot 2

Changing udp port

The default port for BACnet on a CoolAutomation device is 47808. If you would like to change it, follow the steps below

bacnet port xxx (required port number)
OK
Boot Required!
boot 2

 

Changing default instance number (Optional)

By default, the number of instances is set to 64(Hexadecimal = 40). To change the default instance, follow the steps below:

 

bacnet instance xxx (required instance number in decimal)
OK
Boot Required!
boot 2

Enable BBMD support (Optional)


To enable BBMD support and link with a BBMD device (router), follow the steps below
>bacnet BBMD <ip> <port> (required IP and port)
OK
Boot Required!
boot 2
BACnet MSTP Integration

 

Activate BACnet MS/TP

CoolMaster & CoolMasterPro can be configured via the touch screen. Please refer to the CoolMaster user manual and review the BMS setting chapter

 

>line type L3 BAC
OK
Boot Required 
boot 2

 

Changing default Instance (BACnet id/mac address)

 Follow these steps

>line myid L3 xxx (required ID number in decimal)

OK, Boot Required!
Boot 2

 

Changing default Instance number (Optional)

 By default, the number of instances is set to 64

To change the default number, Follow these steps

>bacnet instance 77 

OK, Boot Required!
Boot 2

 

Changing the default MS/TP ID(TS/MAC ADDRESS) – Default is 64 (Decimal)


Follow these steps:


>line myid L3 xxx (required ID number in decimal)
OK, Boot Required!
Boot 2

 

Changing default BACnet frame (optional)

The default BACnet MS/TP frame is:

Baud Rate  9600 bps
Data Bits 8
Parity     None
Stop       1

To change the BACnet format, follow these steps

>line baud L3 19200_8N2
